Split-type assembly real training is the important step of Course of Engineering Graphics teaching, can strengthen the cognition of student to three-dimensional array mode, cultivates body analysis and line surface analysis ability, configuration ability and projection graphic capability.In teaching process, grasp Methods of Scinetific Thinking and carry out real training, to strengthening student's engineering ability and creativity consciousness important effect is arranged, and for follow-up course provides indispensable rudimentary knowledge and basic skills, as seen, split-type assembly real training has irreplaceable effect in Teaching Instruction of Engineering Graphics.

The utility model content

At above-mentioned prior art, the utility model provides a kind of split-type assembly practice-training teaching model, the utility model practice-training teaching model has good fractionation and associativity, can utilize the different assembly of feature unit splicing wherein, the student can temper the reverse thinking ability in multiple physique structure of cognition and array mode.In the utility model practice-training teaching model mentioned to the cell cube with composite unit structure feature be meant the architectural feature unit that assembly is split as least unit.

In order to solve the problems of the technologies described above, the technical scheme that the utility model split-type assembly practice-training teaching model is achieved is: this practice-training teaching model comprises a plurality of cell cubes with composite unit structure feature, be inlaid with magnet in each described cell cube, adopt magnet suction to be connected into an assembly model between each described cell cube.

The utility model practice-training teaching model, wherein, described cell cube is a basic body.Described basic body is provided with and cuts off the plane, cuts off curved surface and one or more surfaces of passing through mutually in the curved surface.

Compared with prior art, the beneficial effects of the utility model are:

The utility model practice-training teaching model is made up of the architectural feature unit of various characteristic feature key elements such as detachable top board, middle solid, floor and base plate, and the student can be spliced into assembly by certain array mode by selecting a plurality of unit voluntarily.With three-dimensional substantially, cut off solid, pass through contents such as solid, assembly and the pattern technique of painting in relevant practice-training teaching, mutually with the organic linking of the curricular system of giving prominence to the key points.

Owing to all be inlaid with magnet in each architectural feature cell cube in the utility model practice-training teaching model, adopt the mode of the mutual adhesive of magnet to connect between each cell cube, sliceablely go out different and effective form that have engineering significance.And the formation of assembly is very flexible, convenient, safety.
